RIOT-2024.04 "UwUtastic" - Release Notes

RIOT is a multi-threading operating system which enables soft real-time capabilities and comes with support for a range of devices that are typically found in the Internet of Things: 8-bit and 16-bit microcontrollers as well as light-weight 32-bit processors.

RIOT is based on the following design principles: energy-efficiency, soft real-time capabilities, small memory footprint, modularity, and uniform API access, independent of the underlying hardware (with partial POSIX compliance).

RIOT is developed by an international open-source community which is independent of specific vendors (e.g. similarly to the Linux community) and is licensed with a non-viral copyleft license (LGPLv2.1), which allows indirect business models around the free open-source software platform provided by RIOT.

About this release

The 2024.04 release, nicknamed "UwUtastic", includes many features and bug fixes. Here are some of the highlights:

RIOT boots on two newly added boards:
- The Nintendo Game Boy Advance (#19519)
- Native on 64-bit Linux / x86_64 (#20315, #20335, #20339)
The documentation features a new guide to help you set up a RIOT develpoment environment on Windows (#20426)
To accommodate the ever growing RAM sizes in the IoT, RIOT can now monitor your malloc usage (#20363)

Dependency modelling via Kconfig is no longer part of RIOT. A big step forward towards having only one source of truth for configurations (#20438)

210 pull requests, composed of 446 commits, have been merged since the last release, and 4 issues have been solved. 42 people contributed with code in 82 days. 2409 files have been touched with 26218 (+) insertions and 29933 deletions (-).
